JAMES J. RICKETTS, OF PITTSBURG, PENNSYLVANIA.

, COUPLlNG FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 515,925, dated March 6,189%.

Application filed April 21, 1892- $erial No. 430,078- (No model.)

To all whom it may concern:

Be it known that 1, JAMES J. RIOKETTS, a resident of Pittsburg, in thecounty of Alla gheny and State of Pennsylvania, have in- 5 vented a newand useful Improvement in Couplings forVVatenOlosets; andl do herebydeclare the following to be a full, clear, and exact descriptionthereof.

My invention relates to the couplings for water closets andlike earthenbowls, by which the supply and discharge pipes are connected thereto.The usual custom has been to employ what is termed a spud for thispurpose, the bowl having a horn provided with I an annular recess havinglips extending inwardly therefrom, and the spud having lugs passingbetween and turned behind the lips, the recess or chamber being thenfilled with sulphur to make a tight joint, and the regu- 2o larconnection being made to the spud. The principal objections to thisconnection were that the coupling was permanent, when made, and that atight joint could not be insured, and the object of the presentinvention is to 2 5 overcome these objections.

It consists, generally stated, in combining with the earthenware horn,an inwardly threaded ring within the mouth of said horn, said ringhaving lugs engaging by a bayonet 50 joint with said horn, a washerfitting against a seat in the horn, and a threaded nipple engaging withthe ring and compressing the washer against the seat of the horn.

To enable others skilled in the art to make and use my invention, I willdescribe it more fully, referring to the accompanying drawings in which-Figures 1 and 2 are longitudinal sections showing two forms of theinvention; and Fig, 3 is a cross section on the line 3-3, Fig. 1.

Like letters of reference indicate like parts in each figure.

The horn of the water closet or other earthenware bowl is shown at a,said horn forming the mouth to the bowl and having the annular recess ordepression I) and the seatc at the base thereof. The horn has also theinwardly projecting lips d at the outer end of the recess to hold thering 6 within the recess, the lugs e on said ring passing through thespaces d between the lips, and the ring being then turned to bring saidlugs back of the lips and retain the ring in the horn by what may betermed a bayonet joint, any equivalent construction being, of course,included within my invention. The ring e is interiorly threaded, and thenipple f screws within the ring as shown. I prefer to employ theinvention with flexible tube connections, such as shown in patentspreviously granted to me, and in that case the nipple has the angularportion g for engagement by a wrench and the nipple fits around the bodya of the rubber connection, and the annular flange 1' thereof extendsoutso as to fitagainst the seat 0 of the horn. Then byscrewing thenipple f through the ring 6 the inner end of the nipple will be pressedagainst the flange 1' which forms a washer to be compressed between thenipple f and seat 0, and so form a; tight joint. Connection can then bemade to the rubber tube or elbow 71. When the rubber tube or elbow isnot employed, a washer is is placed against the seat 0 as shown in Fig.2, and the nipple'f is screwed against 7 5 the washer .to form the tightjoint, and in that case the outer end of the nipple is exteriorlythreaded so as toprovide for the coupling thereto of the pipe or fittingto be connected to the closet. In either casea simple, cheap, andefticient coupling between the earthenware closet and bowl, and thesupply or discharge pipe may be obtained, and one which while insuring atight joint can be removed and replaced at will.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In combination with an earthenware bowl, or like article, having amouth provided with a seat at the base, a washer fitting against theseat, a ring within said mouth engaging by a bayonet joint with thebowl, and a nipple engaging with the ring to compress the washer againstthe seat of the bowl, substantially as and for the purposes set forth.

2. In combination with an earthenware bowl, or like article, having themouth provided with the seat 0 at the base thereof and inwardlyprojecting lips d at the entrance thereof, the interiorly threaded ring6 within said mouth, the lug 8 formed thereon, the
